OPNFV Doctor project started as a requirement project and identified gaps
between “as-is” open source software (OSS) and an “ideal” platform for NFV.
Based on this analysis, the Doctor project proposed missing features to
upstream OSS projects. After those features were implemented, OPNFV installer
projects integrated the features to the OPNFV platform and the OPNFV
infra/testing projects verified the functionalities in the OPNFV Labs.

This document provides an overview of the Doctor project in the OPNFV Euphrates
release, including new features, known issues and documentation updates.

Doctor now supports network state handling where VIM notifies on the actual data
plane port state, utilizing the new feature called `port-dp-status`_ developed
in OpenStack Neutron as the result of our upstreaming efforts.

For Euphrates release, the Doctor project also refactored testing code to python.
